JOHN M. MARTY, OF CLARKSVILLE, ARKANSAS.

COMBINED INJECTOR AND EJECTOR.

ESPECIFICATION formingpart of Letters Patent No. 31* ,595, dated March 31, 1885.

Application filed July 14, 1884. (Modem To all whom it warty concern.-

Be it known that I, JOHN M. lVIARTY, acitizen of the United States, residing at Clarksville, in the county of Johnson and State of Arkansas, have invented certain new and useful Improvements in Combined Injector and Ejector; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to improvements in combined injectors and ejectors, as hereinafter fully described and set forth.

Figure l is an inside face view of the lower half, B, of the body of my double combined injector and ejector,and longitudinal views of the tubes to, b, 0, d, and e, regulating-plug f, steam-head plugs g g, bushings h h, packingglands j j and k, gasket-sockets j j and 7c, check-valve l, and levers M. Fig. 2 is an edge view of my injector, showing its upper and lower halves, A and 13, its studs n n, packingglands j j and 7c, self-stopping overflows 0 and p, 0 being a sectional view showing the head.

19, pin p and stopper 1). Fig. 3 is a detail sectional view of packing-gland k, and a view of the regulating-plug], showing its threaded end f, working in the interior thread, f, of the packing-gland 70. Fig. 4. is a sectional view of forcer-tube a, packing-glands j, sockets j j, gaskets j Fig. 5 is a detail sectional View of steam-head plug 9 and bushing h, circular groove 72?, socket-pin k pin-hole h in said bushing. Fig.6 is a perspectiveview of steam-head plug 9 and bushing h, showing pin-hole h My invention is described as follows: It is made in two halves, A and B, which are substantially joined together by screws or bolts and nuts q, and by the pipe-connections on the threaded ends 1 r. The steam-tube a is fitted into its bed loosely, so that it can be worked backward or forward by the lever M. The tubes b, 0, d, and e have ground shoulders b c to fit into their ground sockets b 0'. These tubes 12 c d e also fit a little loosely in their beds, and are allowed room for a little play between their ground shoulders and the ground sockets b 0, so that the injector will drain itself of water when not in use.

The steam-tube a and regulatingplugf are provided with packing'glandsjj and 7c. The flanges j and 7a of these packing-glands fit into their sockets j and It, said sockets being first partially filled with any proper packing material. These packing-glands are provided with arms having months which are arranged to grasp threaded studs a n These threaded studs are provided with nuts n, which turn against the outer face of the packing-glands j j and 7c, and press them down into their sockets j k.

The steam-tube a is long and cylindrical, and reaches from the steam-chamber A to the mixer-chamber B. This is' for the purpose of keeping the water ascool as possible up to the very nozzle of the said steam-tube, and thus prevent any leakage of steam.

In a slot made between the two halves and B the lever M plays. One end, m, of this lever is pivoted at point m while the other end plays loose in said slot. It has a hole, m, in it, which loosely fits over the steam-tube a, and (the lever) is pivoted to the tube by screws and nuts W. This lever M moves the steam-tube a back and forth and when I wish to cutoff the steam from passing into it I run its rear end back into circular groove h of bushing h, which acts as a plug and closes the said end of said steam-tube. The check-valve Z fits into the outer end of pipe 0, which is provided with perforations Z and pin Z.

The regulating-plug f is screwed into packing-gland k. This packing-gland has arms with mouths which fit onto and grasp studs 11*. These studs 41, have nuts which. work on them and against the outer face of the arms of said gland, and press its flange k into the socket k, and compress any gasket therein contained.

To start the machine, push lever M clear back and give steam. As soon as water appears at overflows, move the saidlever forward until no more water appears at overflow 11. Then turn regulatingplugf forward until no more water appears at overflow 0. When the flow of the water is thus once regulated, it will not have to be moved afterward, except under change of temperature, or from the change of the depth to the water in the cistern from which .it comes, or a large change of steampressure, thus practically making my invention a one-lever injector.

The beds of the bushings h and h have a pin, hflwhich passes into hole k of said bushings, and prevents them from turning while they are being tightened into place by screwing into them plugs g 9. By taking out these plugs g g the whole interior of the machine is accessible by a wire in case any holes should be stopped.

This combined injector and ejector is made in two parts, so that it may be taken apart by unscrewing the screws or nuts and bolts q. When so opened, the whole of the injector can be easily taken apart, as tubes at, b, a, d,

and e fit loosely in their sockets, and packing-glands j j and It will come out of their sockets at once, and the whole thing canbe taken apart at little cost or trouble and cleaned, and, if necessary, repaired.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s

1. The two halves A and B of the body of the combined injector and ejector, each having beds for the pipes a, b, c, d, and e, and for the regulating-plug f, steam-chambers A and B, sockets jk for packing-glands j and 7t. beds for the plugs g g and for the bushings hh, said halves A and B being firmly held together by screws or bolts and nuts q, substantially as shown and described.

2. The two halves A and B, having steamchests A B, beds for the pipes a, b, c, d, and e, the upper half, A, having overflows 0 and 19, said halves being firmly held together by screws or bolts and nuts q, substantially as shown and described;

3. In combination with halves A and B, threaded studs a, with packing-glands j, having mouths grasping said studs n, and flanges fitting into sockets j, with nuts n,working on threaded studs n and against the outer face of said packing-glands j, and adapted to press said flanges down into their sockets j, substantially as shown and described.

4:. In combination with the halves A and B,

threaded studs 92*, with packing-gland k, hav--. ing female screw f carrying threaded regulating-plug f, flange 70 fitting into socket 7t, and nuts n,working on said studs 17. and against the outer face of said packinggland k, and

adapted to press said flange is down into its socket is, substantially as shown and described.

5. In combination .with halves'A and B, lever M, its end at, pivoted on pin m of the lower half, B, of the body, grasping in its perforation m tube a by means of nuts and bolts m and tube a, working back and forth in packing-gland j, and bushing h, having circular groove h fitting the rear end of tube a, and serving as a plug to shut off the steam from said tube, when required, all substantially as shown and described.

6. In combination with the halves A and B,

pins hflwith bushings hand h. fittinginto their grooves, and their pin-holes h, fitting on said pins h, and their shoulders If, fitting against the shoulder of said grooves, and plugs g g, screwing into said bushings, substantially as shown and described, and for the purposes set forth.

7. In combination with the combined ejector and injector, having the two halves A and B,

I steam-chests A and 13 self-stopping overflows end of said pipe, preventing said check-valve from being blown out, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
